A tube or conduit 28 penetrates the wall of the supporting tube 13 and leads to afan housing 29 within which there is arranged a suitable fan 30 driven by small electric motor 3l., Preferably, as shown, conduit 28 passes downwardly through the upper wall of the hollow base 32, and the fan housing 29 and motor 31 are secured to and positioned within the hollow base. With this construction as the roll is closed air-tight except for the perforations through its wall, the fan 30 acts to suck air from supporting tube 13 from the space within the roll and thereby draws air through the l.padding and through the perforations 5 vto effect drying of the padding in the manner described in connection with Figure l.

AlthoughA I have shown and described specific structures constituting embodiments of my invention, I do not 'desire to restrict myself to the details of form, construction or arrangement, as various changes and modifications may be made within the scope of the appended claims.

1. An ironing machine comprising a gear-housing with gearing therein, an external gear driven therefrom, a tubular ironing -roll comprising a perforated metallic shell and padding therearound, a tube rigidly mounted in the gear housing and extending therefrom a distance less than the length of the roll -and disposed within and axially of the roll, aclosure disk for the end of the roll adjacent the gear housing and formed witlrsan internal gear meshing with the said external gear, a bearing disk mounted within the roll intermediate the length of said roll, said disks journaled on said tube, and mechanical means for( withdrawing air from the space within the roll between said disks.

3. An ironing machine comprising a gear housing with gearing therein, an external gear driven therefrom, a tubular ironing roll comprising a perforated metallic shell and padding therearound, a tube rigidly mounted in the gear housing and extending therefrom a distance less than the length of .the roll and disposed within and axially of the rolland having along the length thereof between the disks hereinafter claimed a multiplicity of perforations extending through its wall, a closure disk for the end of the roll adjacent the'gear housing and formed with an internal gear meshing with the said external gear, a bearing disk mounted` within the roll intermediate the length of said roll, said disks journaled on said tube, and mechanical means for withdrawing air from the tube and hence from the space within the roll between said disks.

4. An ironing machine comprising a'gear housing, an elongated tube-rigidly mounted inthe housing and extending laterally therefrom, a hollow-cylindrical ironing roll journaled on said tube for rotation thereon and having a. plurality of perforations extending through its wall,

padding surrounding said roll, and means for withdrawing air from the interior of the roll including an electric motor mounted on said tube within the roll and a fan driven by said vmotor.

5. An ironing machine comprising a hollow base, a 'gear housingmounted thereon, a cylindrical roll, a tube rigidly mounted in said gear housf ing extending laterally thereform and adapted to support said cylindrical roll, and said tube having perforations through its wall, closure disks for the opposite ends of said cylindrical roll, a padding surrounding the roll, a conduit in communication with said tube, and a fan mounted within the hollow `base and in communication with said conduit.

6. In an ironing machine, a hollowlcylindrical ironing roll having a plurality of perforatlons, a tube mounted in said ironing rollV having means extending therefrom and in contact vwith the interior of the ironing roll for the support thereof, a motor and fan mountedin said ironing roll for withdrawing air from the interior of said ironing roll and carrying with it moisture drawn through said perforations, said motor having leads extending thereto through said tube.
